In the context of organisms and biological systems, how does the second law of thermodynamics apply?

Energy is lost in each energy transfer, leading to lower quality forms. (correct)

Energy is generated with each successive energy transfer.

Energy is not used by organisms and is stored for future use.

Energy is conserved and remains at the same quality level.

What defines a population in ecology?

All the different species coexisting in an ecosystem.

The interconnected food chains in a biological community.

All the Trophic levels in an ecosystem.

All the members of a species living in a given area at the same time. (correct)

Soil pH

Energy loss (correct)
